testsuite: Add a test for icon names

This test just checks that all the icon names that GTK uses are present
in the default icon theme.

As icon names are not checked programmatically and we do not want to run
into missing-icon icons in the code, this test seems necessary.

For now, it's just a stub that tests stock icons.
